Abstract: Abstract:Threedimensional model of the natural gas supersonic flow nozzle separation were established. Numerical simulation of nozzle internal flow field via fluid dynamics used software of CFX were conducted . The maher number, temperature, velocity and pressure contours were obtained. The influence mechanism of supersonic flow for the nozzle throat structural parameter variation were announced.
